Interesting.  That would certainly explain why it has not
been made to automatically become buffer-local.

Here is a seemingly relevant entry from src/ChangeLog:

2004-03-02  Kim F. Storm  <address@hidden>

        * window.h (struct window): New member
        overlay_arrow_bitmap.

        * window.c (make_window): Initialize
        overlay_arrow_bitmap.

        * xdisp.c (Voverlay_arrow_variable_list):
        New variable to properly implement and integrate
        multiple overlay arrows with redisplay.

        [...]

Since the restriction seems to have been lifted, I think we
should remove the paragraph that Ryan quoted from the manual
and make the variable automatically become buffer-local.
